Laparoscopic pylorus-preserving pancreaticoduodenectomy (LPPPD) is less invasive than open pylorus-preserving pancreaticoduodenectomy. However, LPPPD has a long operation time with pneumoperitoneum, which may affect the postoperative pulmonary complications (PPCs). We retrospectively evaluated the incidence of PPCs and their risk factors in LPPPD. In 191 patients who underwent LPPPD, the incidence of PPCs was 28.8% (n=55). Multivariate logistic regression analysis revealed that the risk factors for PPCs were male sex [odds ratio (OR), 2.518; P=0.008], high body mass index (OR, 1.172; P=0.024), and low preoperative serum albumin level (OR, 0.390; P=0.032). Length of hospital stay was significantly longer in the PPC group than in the no-PPC group [17 (14 to 26) vs. 14 (13 to 18) d, P<0.001]. There was no difference in the incidence of surgical complications between the PPC group and the no-PPC group (14.5% vs. 6.6%, P=0.096). These results provide useful information for perioperative pulmonary management in patients undergoing LPPPD.
